Shotcrete 101

Shotcrete is a method of applying concrete pneumatically through a high pressure nozzle. Because it is installed at a high velocity, shotcrete tends to have better consolidation than conventional concrete, making for a denser finished product. The consistency of shotcrete is more easily controlled than cast-in-place concrete as it is impossible to place high water/cement (w/c) ratio shotcrete. As a result, characteristics of low w/c concrete are found in shotcrete, including increased durability and reduced shrinkage cracking.  Shotcrete is subject to the same design factors as conventional concrete; therefore, the strength characteristics desired in poured-in-place concrete can also be achieved in shotcrete walls.

Shotcrete offers not only excellent structural properties, but also provides economical advantages over typical cast-in-place concrete. With reduced forming, shotcrete walls can be constructed faster with less material, saving our client both time and money. The absence of tie holes (that need to be filled, leaving visible blemishes) and the ability to easily apply color, stains, and textures makes shotcrete an aesthetically appealing alternative.

Conco operates shotcrete crews in Washington, Northern California, and Southern California. All operators are ACI certified, have years of industry experience, and demonstrate excellent craftsmanship. Our professional estimators can assist you in comparing the time and cost differences of shotcrete walls versus conventional cast-in-place concrete for your specific project.
